Vliv velikosti a expozice holiny na růst kultur douglasky tisolisté

The aim of the study was to determine the effect on the growth of the cultures after the second growing year (coverage) and exposure of clearcuts, seed time and type of used planting material.Totally was measured on four areas - high fence (60x70 m), chopped (25x70 m), underplanting and the large calamity clearcuts. There were represented four different provenance and they were with or without modification of the root system, which were planted in six different dates (spring - autumn). Monitoring and evaluation were especially following features: losses, length of aboveground, increase of the terminal, root collar thickness, length and number of branches, length of needles, color of assimilation system, damage by biotic and abiotic factors. The results of my thesis confirmed that it is best to Douglas fir planted on small regenerative elements with adequate cover of surrounding vegetation. These areas register lower losses and higher increment of above-ground parts. The best planting date is in early spring. It also has confirmed great variability in the requirements for each provenance and Douglas sensitivity to drought. Effect of modification of the root system appears to be minimal.
